Here he is ignoring expert testimony and suggesting that climate scientists, not him, are the ones who are rigid and unresponsive to data: “This very expensive GLOBAL WARMING bullshit has got to stop. Our planet is freezing, record low temps,and our GW scientists are stuck in ice” (January 1, 2014).

Here he is engaging in hasty generalization and confirmation bias (counting the hits, but not the misses, in his pet theory that climate warming is bullshit): “Ice storm rolls from Texas to Tennessee – I’m in Los Angeles and it’s freezing. Global warming is a total, and very expensive, hoax!” (December 6, 2013)

And here’s Trump indulging in a paranoid conspiracy theory that is utterly lacking in the least evidence: “The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive” (November 6, 2012).

This is how Donald Trump thinks–and in a few short months, the only electoral alternative standing between him and the American presidency may be none other than Hillary Clinton.
